Verification Review

This review focuses on style guide claims, justifications, and confidence scores in the provided documents.

---

docs/implementation.md (Line 23)

• Claim:
  This approach is more secure than previous versions.

• Context:

Using JWT tokens, this approach is more secure than previous versions which used session IDs.

• Justification:

The claim is vague and lacks details on the threat model or specific security improvements over session IDs. While JWTs can offer stateless authentication benefits, security depends on implementation specifics such as token expiration, signature algorithms, and storage methods. Without these details, the assertion cannot be reliably verified.

• Requires Verification: Yes
• Confidence Score: 0.6
